I repeat what I said in the first lines. This is the best sound emanating from any headphone I’ve come across.

Usually I’m mostly negative about headphones the first time I hear them and very rarely get wowed right at the off. I eagerly await the release of this headphone as well as the reviews and listening impressions of other headfiers.

To conclude, AKG have finally delivered. Their flagship is here, a £1000 headphone which will establish a concrete place in the listening pleasures of plenty.

CantScareMe,

thank you! You confirm all my impressions I had with the K812Pro!

Heck, literally 6 hours after I last heard the k812, I can still hear it virtually. It’s left that much of an imprint on my mind making it pretty easy I feel to review. Just so memorable.

This feeling I had too, but I wont say it here, some thinks I am crazy

Frequency response is the most useless bit of information for any headphone, it's not like speakers where everything is usually given on a +/- 3db reading.

Hifiman lists their HE-400 as having a frequency response from 20-35khz, while Audio Technica lists their AD700 as having a frequency response of 5hz to 30khz. Does that mean The AD700 can reproduce a 20hz signal 'effortlessly' vs the HE-400? Hell no. AD700 starts rolling off at like 70hz whereas the HE-400 starts rolling off around 35hz. The same can be true for the treble part of the argument as well with different headphones.
